Simulink performance regarding virtual and non-virtual buses

Hi,
I would like to use non-virtual bus objects in Simulink because it gives me a very organized way to duplicate objects multiple times in my model. However, I noticed a HUGE performance loss with bus objects, which I cannot find much information about in the documentation. It is approximately 10-15 times slower than with virtual buses and information stored in the MATLAB workspace instead of the object.
Is this normal? Any ideas on getting around this performacne issue?

Non-virtual buses allocates the memory for the inputs as compare to virtual buses which are just graphical representation and doesn't allocate any extra memory.
So if you are using large number of non-virtual buses in the model with complex hierarchy, it may affect the simulation time. It is completely depends on complexity of model and non-virtual buses in the model.
